The revolutionary Baby Shusher quickly soothes any fussy baby. Developed off the parenting technique in the “Happiest Baby on the Block” book, the Baby Shusher incorporates the fourth ‘S’ of the “Five S’” – shushing. With loud, rhythmic shushing noises, the Baby Shusher draws on ancient, time-tested practices. Plus, the Baby Shusher allows you to set your timing preference with either a 15-minute option or a 30-minute option and it has built-in volume control so that it’s louder than baby’s cries, which is proven to help calm babies. The Baby Shusher is for newborns and up.
